3 member A hinged to the base member and;

adapted to fit thereuponto form the inelosing case and provided with a suitable outlet a; a revolving frame B journaled to revolve within the case and adapted to sustain and rotate within the case suitable detachable appliances as hereinafter specified, whereby. the said machine is made adaptable for the reception and operation of the said several appliances for performing the several operations set forth herein above; and suitable means for rotating the said frame.

My invention also comprises the various combinations and arrangements of parts hereinafter described. i I

More specifically, myinvention embraces the combination with the several elements above specified; of a hollow cylinder 0 formed in two halves c 0' adapted tobe fastened togethenhaving the walls thereof suitably perforated as hereinafter specified and provided with the wings d d arrangedaround the circular wall of the cylinder projecting therefrom outward and inward respectively.

The peripheral wall D of the cylinder is provided with outwardly projecting Wings d arranged oblique to theperiphery of the cylinder and connected with the projecting side rims or walls f which together with the wings and peripheral wall of the cylinder form buckets so thatif the cylinderiis rapidly rotated the water will be carried up and will be thrown from the cylinder by centrifugal force and will strike upon/the balanced-door G and pass out of thecase through the outlet a.

The balanced door G is pivoted near itsmiddle tothe lower margin of the port a and its outer leaf g is heavier than its inner leaf g so that when thrown horizontalas shown in Fig. 4 it will be held in that position by gravity; andthe opening a, is suchthat when the door is thrown vertical as shown in dotted lines Fig. 6, it will slightly overbalance and lean toward the case as shownin dotted lines, Fig. 6, thus to be held in position by gravity.

The peripheral and side walls of thecylinder are provided with perforations e, e to allow the water, steam and air to fiowintothe cylinder.

The means for introducing thesteam, hot

water or air to the lower section A-may be of any suitable construction butlwill now (1e scribe the particular means which I employ.

H is a boiler which sustains the base member or section A of the case. This boiler is adapted to be filled with water and placed upon a stove or range for heating if desired, h being a water pipe through which the boiler may be filled with water. For convenience of heating, this boiler H is provided with a steam pipe or heater I which communicates with a suitable steam generator (not shown), and is arranged in the bottom of the boiler and opens to discharge inside the boiler. The discharge port '11 is arranged near the top of said boiler above the lowest point of the'case so that the steam will contact fully with the bottom of the case in flowing to the outlet.

1" indicates the outlet for the steam from the boiler.

J indicates a steam pipe leading from the outlet 2" into the lower part of the base A of the case.

K is a water. and steam pipe which communicates with the interior of the base A, and

also, through the medium of the steam pipe JV, with the interior of. the base boiler H.

The connection between the boiler H and the pipe K is provided with the curved connection j which resembles in outline an inverted trap whereby the pipe J is connected with the top of the pipe K. The pipe Kcommunicates with a suitable receptacle L which is arranged to receive the water'which maybe discharged through the spout M which leads from the port a. The receptacle L is arranged to revolve in a horizontal plane and is connected by the beltl and pulleys Z Z and shaft 2" with the rotating frame B so that when the frame B is rotated the receptacle L will also rotate. The receptacle L is provided with a suitable drip rack N and is detachably connected with the pipe K to allow the water to flow from the receptacle L down into the pipe K and thus into the case A.

K is a suitable support for the pipe K. and

' receptacle L. The receptacle L is provided with the downwardly projecting pipe or nipple 11 through which the receptaclejcommunicates with the pipe K through the medium of the hollow journal is to which the pulley Zis attached. By this contrivance the receptacle can be removed from the pulley Z upon which it normally res-ts asindica'ted in Figs. 4 and 5 and when in place thereon it can be rotated thereby.

N is a perforated steamdistributing plate which is arranged beneath the drip rack N to distribute the steam and cause it to be appliedto allof the dishes in the pan or receptacle L.

I will now describe the operation of the machine as a dishwasher and drier. The water maybe introduced into the machine through the receptacle L and the pipe K and flows into the bottom of the case. Heat is applied to the case either through the medium of steam introduced through the steam pipe I or by water in the boiler heated by a stove or other convenient means. When the water is suffi ciently heated the dishes to be washed are placed in the receptacle L, care beingtaken to place the same on edge so that water poured on to the dishes from above will flow down through the dishes and into thebottom of the receptacle and thence through the pipe K back into the case the valves is and 7' be ing open and jclosed. The door G is adjusted as indicated in Figs. 4 and 6. The cylinder is then rotated in the direction of the arrow in Fig. 4. The wings d dip'into the water in the case and carry the same upward and a sufficient rapidity of rotation is imparted to the cylinder to cause the same to throw the water from the cylinder on to the door G whence it flows out through the port a down the spout M to fall upon the dishes in the receptacleand into the receptacle L. The receptacle L is placed at a sufficient distance below the end of the spout M to allow a hydraulic force or dashing of .-the falling water to be produced to apply the water forcibly to the dishes for the purpose of cleansing the same. The belt Z isarranged with relation to the pulleys Z and I so that when the cylinder is thus rotated the receptacle L will be rotated in the direction of the arrow shown thereon in Fig. 1 so that as the water falls into the receptacle the dishes The receptacle or pan L is so set with relation to the spout M that the water falling from spout M will fall into that half of the pan which is to the rear in Fig. 1 and to the front in Fig. 2. The water thus applied flows down through the outlet into the pipe K and thence into the base A whence it vis' again and cylinder and thus heating the same inaddition to the heat which is imparted to the water while passing through the boiler or base H. When the dishes have been washed,

the balanced door G is thrown up into the position indicated in dotted lines in Fig.6 so that the water no longer passes downthrough Then the valve 7c is closed and the steam from the pipe J is thus forced to pass up through the pipe K and up through i the dishes in thereceptacle L thus thoroughly rinsing and beating them so that they will readily dry when removed from the receptacle. When the dishes have been thoroughly cleansed and heated the receptacle L can be lifted from its support and carried to such place as the dishes are to be deposited. When the dishes are removed the perforated distributing plate can be removed thus giving access to all parts of the receptacle for i such cleansing as may be required;

The dishes while being washed do not require any handling with the hands and thereforestrong lye or other cleansing solutions may be used which otherwise could not be used withsafety and the dishes can thus be.

thoroughlycleansed from all impurities. The

waterthus charged with the cleansing solutions is not wasted as it returns to the bottom of the case but is used over and over 1 again until great numbers of dishes are thoroughly cleansed. i i

The frame B is provided with one hinged slat or crossbar b fastened by a suitable clasp b and when it is desired to use the appliance as a clothes washing machine, the clasp b is released and the bar I) thrown back as indicated in Fig. 3 thus allowing; the upper section 0' of the cylinder to be removed from the lower section 0 and allowing the clothes to be placed in the lower section, at"- ter which the upper section is replaced and secured by means of the cross bar and clasp. The cover of the case A is then thrown into position shown in Fig. 4 and issecured by the clasp a". The water is then introduced into the case and heated by steam or by the base which is set upon a suitable stove or other heating appliance. The balanced door G is thrown into the vertical position as indicated in dotted lines in Fig. 6 and. the cylinder is then rotated in a direction opposite to the arrow at the top of Fig. 4. The door G prevents the escape of water through the outlet at so that the machine is used without any escape of water. As the cylinder is thus rotated the inner wings d catch the clothes and the water which has entered into the cylinder through the perforations eand e, and carries the same up toward the top of the cylinder until the clothes and water dash back and the upper part of the cylinder 0 is removed thus allowing access to the lower section a of the cylinder in which the clothes 1 remain. By forming the inner cylinder in two halves, when the upper part of the cylinder is removed theclothes in the lower part I of the cylinder are thus arranged in convenient position to be removed therefrom, and greater-convenience of operation is secured than is possible where the cylinder is simply provided with a door through which the clothes are introduced into and removed from the interior of thecylinder. This featureis very important, and relieves the operator of a vast amount of work, and the danger of scalding the hands, which is present where the clothing must be removed from the cylinder through a comparatively small door or opening therein, as has heretofore been proposed. A clothes wringer Q is then attached to the case close to where the cover A is hinged and the clothes are then passed through the wringerinto the cover A which serves as a receptacle therefor. The water from the wringer flows back into the case A fromwhich it can be drawn oft. Whenthe clothes have been thuswru ng the wringer is removed and the clothes are returned to the lower section 0 of the cylinder and the upper section c of the cylinder is replaced and secured by the bar and clasp. Then the cover A is adjusted to the position shown in Fig. 1 the steam heat being applied from the steam generator (not shown) to the base of the case. The steam is shut off from the interior of the case and the valve h is opened to allow the steam'to escapethrough' pipe 71,. The draw off 0 and the port aare opened thus allowing a draft of' air to flow in at O and out at a. The cylinder is then rotated in the direction indicated by the arrow in Fig. a thus carrying the clothesup and causing them to drop within the cylinder while the rotation of the cylinder causes a blowing action which carries off the vapor and steam through the port 0; thus rapidly drying the clothes. When the clothes are thus dried the machine is opened again and the clothes are removed.

The machine as arranged and shown in Fig. 4 can easily be applied for the purpose of washing potatoes by operating the machine in practically the manner above described for washing dishes.

The machine canalso be used for cooking potatoes and other vegetables in large quantities by placing the same in the cylinder and turning on steam through the pipes I, J and K into the case.
